Flat Roof Leak Repair in Los Gatos, Campbell, CA
Flat roofs don't leak like pitched roofs — water travels further and hides longer before it shows inside. Roof Leak Repair Masters is the local licensed expert for flat roof leak repair in Los Gatos, Campbell, CA. Older homes here often feature clay tile or wood shake with aging underlayment.
Flat roof leak repair is membrane work: finding the breach in your TPO, EPDM, modified bitumen, or built-up roof and restoring it watertight. We use electronic and flood testing to locate the entry, then patch, re-seam, or re-flash with heat-welded or adhered materials matched to your system. Hillside properties above town face runoff concentration and Santa Cruz Mountain weather exposure.
Ponding Water: The Los Gatos Problem
If water stands on your roof more than 48 hours after rain, you have a drainage problem that will defeat any patch. Los Gatos is the affluent adjacent town with a historic downtown and 1920s–50s homes plus hillside estates. We assess slope and drains with every flat-roof call.
Solutions range from clearing and re-sealing drains to tapered insulation or crickets that restore positive drainage. Fixing the ponding is often more important than patching the current leak.
- Tapered insulation for dead-flat areas
- Crickets to divert around curbs
- Drainage fix prevents the next leak
- 48-hour rule for ponding
What Flat Roof Repair Costs in Los Gatos
Simple membrane patches are affordable; re-flashing a curb or parapet section costs more; fixing drainage with tapered insulation is a bigger project — but all are fractions of premature replacement.
Because diagnosis is the hard part, our detection fee is credited toward the repair. Hillside properties above town face runoff concentration and Santa Cruz Mountain weather exposure. Call (888) 974-0663 for a free assessment.

How We Find Flat Roof Leaks
We start with a systematic membrane inspection — seams, flashings, penetrations, drains — then use moisture scanning to map trapped water and isolate the breach zone. For stubborn leaks, controlled flood testing pinpoints the entry.
This methodical approach is why we find leaks that two previous contractors missed. Older homes here often feature clay tile or wood shake with aging underlayment. Guessing on flat roofs just doesn't work.

Yes — Older homes here often feature clay tile or wood shake with aging underlayment. our flat-roof crews handle both residential low-slope and commercial buildings.
Why is the stain so far from where you found the leak?
Water travels between the membrane and the deck on flat roofs — sometimes dozens of feet — before it finds a way inside. That's exactly why flat roofs need professional detection rather than patching above the stain.
My flat roof ponds water — is that normal?
No. Water standing more than 48 hours after rain accelerates membrane failure and voids many warranties. We assess and fix drainage as part of leak repair.
